How to care for hydrangea in winter

Are hydrangeas afraid of freezing?

Hydrangea is not cold-resistant. The temperature of its maintenance environment should not be lower than 5℃ when it enters winter after its leaves fall, otherwise the plant will easily be frozen to death. Its suitable growth temperature is between 18-28℃.

How to care for hydrangea in winter

Temperature: If you want the hydrangea to continue growing in winter, it is recommended to move it indoors and keep the temperature above 5°C. If you want it to spend the winter safely, the temperature needs to be kept above 0°C.

Sunlight: In winter, hydrangeas should be placed in a sunny place as much as possible. This will allow them to synthesize more nutrients, which is better for them to survive the winter.

Sunbathing : Hydrangeas cannot tolerate the cold. The sunlight intensity is weak in winter, so hydrangeas can be exposed to more sunlight. Sunbathing can increase the growth temperature and improve its cold resistance.

Watering: When the temperature drops, you need to control the water. Unless the soil of the hydrangea becomes very dry, there is no need to water it. This can prevent the water that it cannot absorb in time from accumulating in the soil and causing it to be waterlogged.

Fertilization: In winter, hydrangea grows slowly, so no fertilizer is needed. However, if the temperature where it is maintained can be maintained at around 20℃, you can also apply a little liquid fertilizer.

Hydrangea Care in the North

After hydrangeas shed their leaves in winter, the temperature needs to be controlled above 5°C. Indoor potted plants in the north will enter a dormant state in winter, and the potting soil should be slightly dry. If it is too moist, the leaves of the plants will easily rot.

Precautions for growing hydrangea in winter

1. In the southern region, hydrangeas do not need to be placed indoors, because the high temperature indoors will affect their flowering time. If you want hydrangeas to grow well, you only need to keep the plants growing in an environment with sufficient light, otherwise it will not be conducive to their blooming next year.

2. Hydrangea seedlings planted in the ground are the most cold-resistant, while potted hydrangeas are the least cold-resistant. If they are potted hydrangeas, they can spend the winter outdoors in the southern region, but in the northern region, they must be moved to a relatively warm place on the balcony to spend the winter.

3. Hydrangeas are easily infected by cold winds when the weather is cold. They need to be kept warm in winter. Of course, they should not be placed in a greenhouse, otherwise the temperature will be too high, which will affect the dormancy of hydrangeas and eventually affect their flowering.

4. When the temperature is too low in winter, you can cover the bottom of the hydrangea's rhizomes with some felt, or some peat soil or rotted sawdust. This will keep the flowers warm and allow them to bloom more.
